Hopefully you will too.





In my second full year of flying my 20, around 175 hours, only thing I

disagree with in these note is regarding flap setting for thermalling.

I nearly always use 4 at about 42 kts empty and 46 kts with water and it

seems to me to climb better than with setting 3. Mine is an early 20 with

winglets. Be interested in the nopinions of other 20 owners.

I thermal always at setting 4, speed and turn radius is less than with flaps at 3. When dry, I cruise usually 130-150 kph in weak weather (flap 2), 150-180 in stronger weather (flap 2, at 170+ kph flap 1). Ballasted, I adjust speeds +10-+20 kph upwards. Landing always at flap 4.5, never anything else. I recommend always landing at same configuration. It seems to be quite popular to invent new flap settings for landing with ASW20. Thank god it is forgiving aircraft.
